Question

我想创建一个水平列表视图的垂直列表。我已经使用this实现了它。但是我的问题是每个项目都在水平方向分别滚动，我不希望这样。我需要完整的回收站视图一起水平滚动。这是我正在使用的代码。

ListView.builder(
                itemCount: memberItemArray.length,
                shrinkWrap: true,
                itemBuilder: (BuildContext context, int index) {
                  return SingleChildScrollView(
                    scrollDirection: Axis.horizontal,
                    child: Row(
                      children: <Widget>[
                        scrollItem(
                            75,
                            const Color(0x00FFFFFF),
                            const Color(0x50000000),
                            memberItemArray[index].sID),
                        scrollItem(
                            200,
                            const Color(0x00FFFFFF),
                            const Color(0x50000000),
                            memberItemArray[index].sName),
                        scrollItem(
                            150,
                            const Color(0x00FFFFFF),

经过2天的研究，我终于得到了答案。只需使用 SingleChildScrollView 作为提供滚动方向为水平方向的父级，它的子级将是一个大小框，其 width 将是 static ，正如我所知道的那样列表视图的宽度，并在此大小框内，我们可以直接使用ListView.Builder和此ListView.Builder的子级，它很简单 Row

SingleChildScrollView(
                    scrollDirection: Axis.horizontal,
                    child: Container(
                      margin: EdgeInsets.only(left: 5, right: 5),
                      child: SizedBox(
                        width: 975,
                        child: ListView.builder(
                            itemCount: memberItemArray.length,
                            shrinkWrap: true,
                            itemBuilder: (BuildContext context, int index) {
                              return Row(
                                children: <Widget>[
                                  scrollItem(
